Nikola Z. Ivanov 35eaa6d8d6 netdevsim: zero initialize struct iphdr in dummy sk_buff ...

Syzbot reports a KMSAN uninit-value originating from
nsim_dev_trap_skb_build, with the allocation also
being performed in the same function.

Fix this by calling skb_put_zero instead of skb_put to
guarantee zero initialization of the whole IP header.

Fixes: da58f90f11 ("netdevsim: Add devlink-trap support")
